DUST-SUCKING APPARATUS `FOR AUTOMOBILES.

To all (whom 15 may concern.'

Be it known that I, MAX' BRENNEISEN, a citizen of the Republic of Switzerland, and resident of Berne, in the Canton of Berne, Switzerland, have invented certain new and useful Improvements in Dust-Sucking Apparatus for Automobiles, of which the following yis a specification.

The present invention relates to dust-sucking' apparatus for automobiles and more particularly for heavy motor-lorries, and its characteristic features are, firstly, the provision at the underside of the chassis of at least one dust-collectingreceptacle having a series of vertically disposed and movable sieves or sifting plates mounted therein, one sieve behind the other and each of finer quality than the preceding one; secondly, at least one suction pipe connected to and made to communicate with the receiving end of the receptacle and having a mouth-piece which is hinged to the free end of said pipe and adapted to `be adjusted from a horizontal position to a position in which it follows the curvature of the lorry-wheel to a point near the ground; thirdly, a ventilator mounted atfthe rear end of the row of sieves and adapted to discharge the dust-freed air into the atmosphere; fourthly, gearing to actuate theventilators,l which gearing is coupled to and made dependent from the motorshaft; and lastly, means to enable t-he driver of the lorry to shake the sieves, to discharge the contents of the dust-collecting receptacles, and to stop the ventilators.

In 'order that this invention may be clearly understood reference is made to the accompanying drawings, in which Fig. 1 represents a cross-section, partly in elevation, of a lorry with the dust-sucking apparatus applied, certain partsy of the motor lorry being omitted;

Fig-2 shows a sideelevation of the same,

the two ,ventilators hereinafter described.

' Ihe rotation of this shaft and the ventilators 1s effected by means of worm-wheels 8y mount-'- ed on 'said shaft 7 and the motor-shaft 2 respectively.

ner of pendulums, five sieves Vor` sifting- Y At each of the ends and within the receptacles are suspended, in the man-y plates 9 of which that nearest the end of the receptacle 6 is comparatively coarse, each of the succeeding sifting-plates being of finer quality than the preceding one. A rod 1 0 extending longitudinallythrough and bearing in the lower portions of the end walls of the receptacle is provided with a number of flanges 11, one such langebeing situated at either side of each of the siftingplates 9 so that when the said rod is moved to and fro, the iianges are caused to knock *latter in this way being enabled to actuate the sieve-shaking device as and when de-' sired. j I

The ends of the receptacles 6 are furthermore connected to and made to communicate withsuction-pipes 12 of-which the mouthpiece 13 is soconstructed that it is adapted to iitclose to the corresponding lorry-wheel, the end of the mouth-piece reaching hereby to a point near the ground. Each .mouthpiece is4 moreover made toform part of a sleeve 14 rotatably mounted at the end of the pipe 12 so that the vmouth-pieces may be lifted into the position shown in dotted linesk in Fig. 2. For such purpose Iprovide each of the sleeves 111 with a projection 15 to which is linked a rod 16, this rod in turn being connected with the slottedvend 19 of a llever- -arm 18 liXed upon a shaft 17 which is mount-,L

ed transversely of the drivers. platform. A lever 2O secured to the shaft 17 in a central positionthereof makes it possible fory the' driver simultaneously to move all the rods 16 and consequently adjust all the mouthpieces of the pipes 12 at the same time. The lever 20 is double-armed its downwardly eX- tending arm 21, by `means of a .controlling rod 36, being connected with one part 22 of a coupling on the motor-shaft 2. This part 22 is adapted to be adjusted on said motorshaft by a nut and spring (not illustrated),

24 designed :to fshut the receptacle tightly,

andhinged to the ends thereof, as at 25, in such a manner, that they arev adaptedto loe opened andclosedtogether, F ig. l. One of the rods y25 serving as'hinges for the trapsV 24, bymeansrof a wire or Vrept-27, 1s connected with a draw-bar having a handle 2S, the rope 27 'being guided by `rollers 26 and the said/draw-bar being mounted in and guidedfbya support 29 arranged close to the seat of the driver. This draw-bar may be adjusted and secured in two positions, namely, in a lower position corresponding with the open position of the traps 24C and in a top position in which the trapsare closed.

Each 'dust-collecting receptacle 6 possesses a ventilatorB() with a suitable housing therefor. Both these ventilators are mounted on thecommon shaft 7 and so tted to the inner v side walls of the receptacles that the dustcharged air, 4when the mouth-pieces 13 are in the position shown, is caused to be sucked from vboth ends of the receptacles through the pipes 12 against' the sifting-plates S) Where the air is freed from the dust and caused to be discharged at the `periphery "of the ventilator vanes into the atmosphere.

Between the series of sifting-plates arranged ateitherend of the receptacles there is achamber 3l `into which projects ,a sieve 32 `of truncated shape forming part of or being attached to the inner wall of the receptacle. Thissieve thus prevents the'penetration from the receptacle into the ventilator :housing of any refuse and Vin order always to keep the sieves 32 clean, a tapered brush is fixed on the ventilatorshaft l'r' which brush, during the action of the ventilators, continuously frees the sieves 32 from .dust y ishereby provided with openings .through which the vpureair may enter unl'iindered.

' And in order to prevent the penetration of larger pieces of refuse such as leaves or paper `into the mouth-pieces 13 the latter are fitted at their faces with a wire or the like netting, while dust-sweeping brushes 3a are secured to the chassis of the lorry in such a waythat the-said nettings, when the mouthpieces are raised into the positionindi'cated in dotted lines, Fig. 2, are cleaned `by the brushes 34.

1T he truncated vbody of the brush Having thus fully described my said vinvention --what I claim and desire to secure by Letters Patent is l. In .the herein-described dust-sucking apparatus for automobiles, ,thecombinatiom of at least one dust-collecting receptacle 4mounted at Ythe underside of the chassis of the automobile, a series of sifting-plates arranged within and at each end oftjhenreceptacle and pivotally suspended from the top thereof, a suction-pipeconnected to and communicating witheachend of the receptacle, a mouth-piece hinged to the free endof 'each' ofthe suction-pipes and arranged closefto the wheel of the automobile, a ventilatorpand housing therefor mounted-atthe rear of the series 'of sifting-plates and communicating with the receptacle, means -to aotuate 4and stop the ventilators, me'ans'to shake the sifting-plates, and means to discharge the contents from the aforesaid receptacle 2.
